Application filed May 10, 1922.

To all whom it may concern:

Be it known that LGEORGE WV. lVLALLORY, a subject of the King of GreatBritain and Ireland, residing at Blenheim, in the Prov- Since of Ontarioand. Dominion of Canada,

have invented certain new and useful Improvements in Doorchecks, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

The invention relates to door checks of that type designed for assistingthe complete closing of the door and the holding of the same tightlyclosed, said check being automatically reset upon the opening of thedoor. The present invention is in the nature of an improvement upon theconstruction forming the subject matter of a prior Patent No. 1,190,313,issued to me on July 11, 1916, and the invention consists in variousfeatures of construction as hereinafter set forth.

In the drawings:

Figure 1 is a longitudinal section through the check in set positionready to function in the closing of the door;

Figure 2 is a perspective view of one of the members of the checkdetached;

Figures 3 and 4 are enlarged sectional views showin the manner ofattaching the roller journa s to the frame;

Figure 5 is an enlarged elevation showing the detachable pivotalconnection between the rockable frame and stationary frame of the check.

In common with the construction shown in my earlier patent my improveddloor check comprises a stationary frame or bracket A and a rockablemember B pivotally engaging said bracket and carrying roller bearings Cand D for engaging the door. The member B is so fashioned that, in theposition shown in full lines in Figure 1., it will hold the roller C inthe path of the door and the roller D so as to clear the edge of thedoor. A spring E is attached at one end to an inturned ear F on themember A and at its opposite end to an inturned ear G on the member B,being in the position shown in full lines in Figure 1 on one side of thepivot and operating to yieldably hold the parts in the position shown.l/Vhen, however, the door such as H strikes against the roller C, itwill swing the member B to shift the spring onto the opposite side ofthe pivot, whereupon the roller D will engage the outer face of the doorand the tension Serial No. 559,738.

of the spring will operate to press the door tightly against the jamb.

The construction as thus far described is substantially that shown in myformer patent and the improvements which form the subject-matter of thepresent invention are as follows In my former patent the rockable memberwas attached to the stationary bracket by eye rivets. This requiredfirst forming the bracket member with flaring or divergent sides andthen in assembling, first registering the rockable member with thebracket and then closing the latter a on said member and rivetingtheparts together With the present construction I have greatly simplifiedthe assembly operation by substituting segmental pivot bearings for theeye rivets upon the rockable member, thereby permitting of completelyforming both parts and subsequently engaging the same with each other.Thus as shown in detail in Figures 1, 2 and 5, the member B has its sideportions B and B formed with open segmental bearings I for engaging thepivot J on the bracket member. The bearin s I have turned flanges K forincreasing t eir width and the pivot bearing J is also formed by apressed flange on the bracket member. The direction of opening of thebearings I is such that the tension of the spring E is always exerted tohold said hearings to the pivots, and consequently, there is no dangerof accidental disengagement of the parts.

Another feature of improvement is the manner in which the journals forthe rollers C and D are attached to the member B. This is accomplishedby forming the journal pins L with grooves M near their opposite endsand by forming the sides of the member B with struck-out and aperturedflanges N, the diameter of the aperture in these flanges N is originallylarge enough to pass over the end of the journal pin L, after which theflanges are flattened down, resulting in the contraction in diameter ofsaid aperture and the firm engagement of the metal side with the grooveportion M of the journal. Thus, as shown in Figure 3, the struck outflanges N are initially engaged with the grooved portions of the ournalL, while in Figure 4 said flanges have been flattened down and aresecurely engaged with the journal.

This feature of construction also simpli fies the manufacture andassembly of the parts in that the rolls and the journal pins may beeasily engaged with the member B, while the flanges N are in struck-outposition, after which the flattening operation will secure the partsfrom disengagement.

Inasmuch as the selling price of articles of this character isrelatively small, it is obvious that these simple improvements, whichlower the cost of manufacture, are of great value in increasing themargin of profit, while the resulting structure is equally good orbetter than that of my earlier patent.

It will be noted that in engaging the journal pins with the side membersB, there is a shoulder on the pin adjacent to the groove N against whichthe n'iargin of the struckout apertured member rests. This facilitatestheclosing in of said member and dispenses With the necessity of using aspecial tool. l urthermore, when the struck-out portion is pressed in,it will so firmly engage the 'bottom'of the groove as to securely lockthe journal from turning.

That I claim as my invention is:

1. A door check comprising a bracket member and a rockable member, theone embracing the other, a struck-out pivot flange on the one member,and a segmental struck-out pivot flange on the other member laterallyengageable with said first-mentioned flange.

2. A door check comprising a bracket member and a rockable-member, theone embracing the other, ears on said members forming attachment meansfor a tension spring, a struck-out pivot flange on one of said membersand a segmental pivot bearing on the other of said members, said partsbeing laterally engageable with each other and the tension of saidspring operating to hold the parts in engagement.

3. A door check comprising a bracket member and a rockable member, eachformed of pressed sheet metal, and the one embracing the other, earsupon said members, a tension spring engaging said ears, an annularstrnck-out flange on one member forming a pivot, and a segmentalstruckout flange on the other memberv forming a bearing for said pivotlaterally engageable therewith, the tension of said spring holding saidsegmental bearing in engagen'ient with the pivot bearing.

4. In a door check, the combination with spaced side members, of aroller arranged therebetween, a journal pin for said roller extendingthrough the same and through registering apertures .in said sidemembers, said pin having a groove adjacent to the end thereof in whichthe apertured side member is contracted.

5. A door check comprising a bracket member and a rockable member, theone embracing the other, a pivot on one member, the sides of the othermember having open segmental pivot bearings engaging said pivot, andspring means for shifting said rock able member andfor'holding saidsegmental bearings in engagement with said pivot.

In testimony whereof Iafiixmy signature.

GEORGE WV. MALLOBY.
